Steps
Segregate oxidizers (chlorine products) from acids (muriatic/dry acid) and from other reducing agents at all times — never store or transport them in contact, since acid-chlorine contact can generate chlorine gas and combustion risk
Keep chemicals in their original, labeled, corrosion-resistant containers with GHS-compliant labeling intact, and maintain accessible safety data sheets (SDS) for every chemical carried or stored, per OSHA Hazard Communication Standard requirements
Store chemicals in a well-ventilated area within the manufacturer's specified temperature range, off direct floor contact where flooding/moisture risk exists, and away from ignition sources
Use separate, clearly labeled physical separation or secondary containment for incompatible chemical classes, and never mix leftover/unknown chemicals when disposing of them
Follow OSHA PPE and handling requirements when transferring or mixing chemicals (eye protection, gloves, and, for concentrated acid/chlorine handling, appropriate respiratory protection where required)
Transport chemicals in a vehicle in a way that keeps oxidizers and acids physically separated and secured against tipping/leaking, applying the same segregation principle used in fixed storage
Known gotchas
Calcium hypochlorite and muriatic acid in direct contact is a well-documented cause of chlorine gas release and fire — this is the single most important segregation rule on a pool route vehicle or storage room
Wet cal-hypo or chlorine tablets left in a sealed, humid, or hot storage area, including a closed vehicle in summer heat, can self-heat and combust even without contacting another chemical
OSHA HazCom labeling/SDS requirements apply to employer-operated service businesses transporting/storing these chemicals, not just fixed commercial facilities
